JasperException

[sreejith panampilly]

Tomcat5.5 and Mysql 5 and am using jakarta-struts-1.1. When I try to access the welcome file, which is index.jsp, I get the following error:

Request all you guyz to provide me with a solution.
Thanks in advance

That init method has this code:

           processWebDotXml();
            scanJars();
            processTldsInFileSystem("/WEB-INF/");
     

So I am guessing the problem may be:
1. tdl location information in web.xml
2. some problem with .tdl files under your application's /WEB-INF/ directory structure
